How to revert the changes which was already committed in a branch?

Summary:

How to revert the changes which was already committed in a branch?

Example:

I migrated 10 Core HR pages to Redwood, all the changes are completed, committed, deployed to multiple environments. Now there's a specific page which is not working as expected and raised SR to Oracle but no solution, support team is not taking it seriously and not addressing it instead they are just updating the SR to push it to customer.

Now i wanted to revoke the changes of that particular page alone so that i can push the other changes, how to achieve it?

Any suggestions please, all the changes are made in single branch.
